...reates the same instructions as variant2 CallInst *AddOv = IRB.CreateBinaryIntrinsic(Intrinsic::uadd_with_over flow, Counter, ConstantInt::get(Int8Ty, 1)); AddOv->setMetadata(M.getMDKindID("nosanitize"), MDNode::get(C, None)); Value *SumWithOverflowBit = AddOv; Incr = IRB.CreateAdd(IRB.CreateExtractValue(SumWithOverflowBit, 0), IRB.CreateZExt(IRB.CreateExtractValue(SumWithOverflowBit, 1), Int8Ty)); So - How do I have to write the code that the target code has a chance of being generated? For me its the same result on LLVM 6.0 and 7. Alternatively add BYTE PTR [rsi+rdi*1],0x1 adc BYTE PT...

Thanks for the help. I’m thinking the same way. Now I’m stuck with how to create a struct; I know how to create a

Emitting calls to these functions (written in an .ll file linked in) works fine, and does the right thing. %Any = type { i8*, i32 } define dllexport void @setGlobal(%Any* %ptr, %Any %value) { store %Any %value, %Any* %ptr ret void } define dllexport %Any @getGlobal(%Any* %ptr) { %val = load %Any, %Any* %ptr ret %Any %val } Trying to replace the setGlobal call with what should be
